The reason was as follows: “He is a director, owner of his own business, and I'm a simple manager”.
In my opinion, the appearance of such fears is absurd. The director is not an omnipotent person, he also needs specialists. If he had the time, knowledge and desire to independently implement the project, would he turn to you? Probably no!
Do not be afraid to share with your clients your experience, opinion and listen carefully, analyze what you are told. Each of you is a professional in your industry, and only joint, equal work on the project will bring a result that will suit everyone.
